Look for increasing development of bioplastics for the medical market. In one of the more interesting announcements at last month’s MD&M show in Anaheim, CA, Arkema said it is in the process of developing a sustainable, bio-based acrylic polymer for medical devices that will feature extremely high impact strength. Introduction is scheduled for mid-2011.
No details are currently available, but it’s expected the compound will be an acrylic blended with polylactic acid (PLA), possibly in the 20 to 40 percent range. That route would be no surprise because Arkema is a major developer of additives that boost performance (particularly impact resistance) o of PLA, which is a thermoplastic aliphatic polyester derived from corn starch, sugar cane, and other crops, even tapioca.
Arkema scientists are looking for feedstocks that could produce acrylic in place of methyl methacrylate (MMA), which is in very short supply. Demand for MMA is rising, but supply is declining due to plant closings. Major chemical producers, such as Dow, are putting less emphasis on bulk petrochemicals. Climate change is also an issue in the biomonomer development, but not the key driver.
A recent report sponsored by the American Chemistry Council (ACC) focuses on emerging gasification technologies for converting waste into energy and fuel on a large scale and saving it from the landfill. Some of that waste includes non-recycled plastic.
Capping a 30-year quest, GE Aviation has broken ground on the first high-volume factory for producing commercial jet engine components from ceramic matrix composites. The plant will produce high-pressure turbine shrouds for the LEAP Turbofan engine.
Seismic shifts in 3D printing materials include an optimization method that reduces the material needed to print an object by 85 percent, research designed to create new, stronger materials, and a new ASTM standard for their mechanical properties.
A recent study finds that 3D printing is both cheaper and greener than traditional factory-based mass manufacturing and distribution. At least, it's true for making consumer plastic products on open-source, low-cost RepRap printers.
For industrial control applications, or even a simple assembly line, that machine can go almost 24/7 without a break. But what happens when the task is a little more complex? That’s where the “smart” machine would come in. The smart machine is one that has some simple (or complex in some cases) processing capability to be able to adapt to changing conditions. Such machines are suited for a host of applications, including automotive, aerospace, defense, medical, computers and electronics, telecommunications, consumer goods, and so on. This discussion will examine what’s possible with smart machines, and what tradeoffs need to be made to implement such a solution.
